21. Homework Make up triad 2 work for the semester due Nov 13. Study vocabulary

22. Today’s Work Notebook review. Ice lab part 2

23. Lab 2 Measuring mass of dry ice Calculate the mass of the ice: Tare = weight of beaker Balance reading tare =______ Balance reading gross = ____ Subtract gross-tare = net = mass of ice

24. Lab 2 Melt rate of dry ice 1.Find the mass of the Dry ice 2.Measure 4 minutes melt time. 3.Re measure the mass. 4.Subtract mass 2 from mass 1, and calculate the seconds 5.Divide the loss mass by the seconds = melt rate in g/s

25. 1. Place measured dry ice into cup. Add ½ cup of water. Observe & record. 2. Add 3 drops of soap. Observe & record. 3. Break up dry ice, and place into water bottle. Add ¼ bottle of water and quickly attach balloon to bottle top. 4. Time 3 minutes and tie off balloon.

26. 5. Inflate balloon via mouth to same size as CO2 balloon. Tie off. 6. Measure diameter of each. Set aside until tomorrow.
